What I ride and why 20" wheels.

Thanks for the info Boyntonstu.

Wide enough 20" rims can mount 16" moped tires rated at 70 mph.

48 spoke wheels are cheap.

Thank you for something I never knew.

Have you done it?

48 spoke wheels are cheap. And strong.

I would imagine that a 48 large gauge spoke wheel would be quite rugged.

This is what I bought:
Shinko SR714 F/R Moped tire - 2.25L-16/Black
rated for over 70 mph.

They fit nice on 20" cheap bmx 48 spoke steel rims, the sides (that contact the brake blocks)
are more sloped than Aluminum ones.

Sidewalls are thicker than bike tires, tread not so much.

I did use some heavier than normal tire irons.

Wow! Terrific!

What engine and how is it mounted?

And, of course, how fast does it go?

I bought 4 tires to get free shipping.
I wanted to mount them to find out if they fit that narrow a rim. I have not run them.
I weight 230 and am looking for cheap bullet proof wheels.

Looking to do a rear rack, 35 to 45 mph.

I would imagine that a 48 large gauge spoke wheel would be quite rugged.

2" steel rims, 14 mm axle, 12 gauge spokes would be would be bomb proof.
Used moped wheels might be cheaper and stronger.

I immediately thought about Stu when I saw this hotrod 20" bike on Gizmag. It has a carbon fiber frame and weighs under 19 lbs.

You need to be careful what type hinge is on a folder you're going to motorize.The above is not what I would use, too much chance of failure with the added stress.Good folder design is "Bike Friday" and my favorite "Raleigh Twenty".
